The Pittsburgh Pirates have acquired first baseman Justin Morneau from the Minnesota Twins in a waiver trade for 28-year-old outfielder Alex Presley, according to multiple reports.

The 32-year-old Morneau is hitting .259 this season with 17 home runs -- including 10 since the All-Star break -- and 74 RBI. Pittsburgh had been linked to Morneau since before the July 31 non-waiver trade deadline, looking to boost an offense that ranks 10th in the National League in runs per game.
